[Peripheral neuroepithelioma]

Neuroepithelioma of the soft tissues of the right parietotemporal region in the 25-year-old male patient is described. The tumor grew through the cranial bones into the dura mater. The patient died 1.5 months after the appearance of the first clinical signs of the disease of brain edema and invasion of the cerebellum into the great foramen occipitalis with compression of the medulla oblongata. The histological structure of the tumor and expression of neuron-specific enolase, synaptophysin, S-100 protein and glial fibrillary acidic protein by tumor cells prove its neurogenic origin.
